' the borough of Manhattan, city of New l York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

My invention relates to typewriting ma: chines and more particularly to tabulating mechanism.

The invention, from certain aspects, may be said to be in the nature of an improvement on the' construction disclosed in my application, Serial No. 730,350, filed November 9th,.1912. y

The objects of the invention, generally stated, may be said to be. as follows :-`(1st) to rovide an improved combined denominatlonal and column selecting mechanism which is comparativelyfsimple in construction` ,and is reliable and'ecientl in use; (2nd) to provide .improvements by which the tabulating mechanism-inthe ordinary operation thereof is necessarily operable alternately as a coliiinnjselectorjand as a denominational selector; (3rd)- to provide means by which the same tabulator keys in the ordinary operation thereof are necessarily operable alternately for column selection and for Adancinirrational selection; (lith.)- to provide automatically operating means controlled by the tabnlator keys for rendering the keys operative at one time as column selecting keys and at another time as denominational selecting keys;A (5th) to provide a series of yind'ependently operable tabulator'stops and automatically operating Ameans by which the same stops are rendered operative at one time as column selecting stops and at another time as denominational selecting stops; (6th) to provide improved tabulatorvmechanism comprising a member which has .a limited movement and may be connected to move in unison with'the carriage or freed from` operative connection with the carriage to enable the latter to move independently of said member, together with key controlled means for variably arresting said member to control the position of arrest of the carriage as determined by the extent of' movement of said member in unison with the carriage; (7th) to provide improved automatically actuated tabulator indicating means; (8th) to provide automatically o erating indicating means for exposing di erent characters of tabulating indices at alternate 'actuations of the tabulator mechanism; (9th) to provide key controlled means'- for shifting a tabulator index; (10th) to provide means by which the'tabulating indicating means may be automatically shifted or may be shifted atwill, as may be desired; (11th) to so construct any and all of the above mentioned means that they may be readily embodied in existing forms of typewriting machines Without changing, or materially changing, the structural features of said machines as they now exist.

To the abovevand other ends which will l hereinafter` appear,` my invention consists in the features of construction, arrangements of parts and combinations of devices to vbe set forth in the following description and particularly pointed out in the append'- ed claims.

ln the accompanying drawings in which like reference characters designate like parts in theV various views, Figure 1 is a fragmentary side view, partly in section, of a type- Writing machine embodyingv my invention, the Ysectioning of the parts at the base of the machine being taken on a line w-w in Fig. 2 and looking in the direction of the arrows at said line. FigQisafragmentary horizontal sectional View of the same taken on the line :v of Fig. 1 and looking in the direction of the arrows at said line. Fig. 3 is a detail fragmentary vertical transverse sectional View, with parts omitted, the section being taken on the line g/-y 'of Fig. 1 and looking in the direction of the arrows at said line, theview disclosing parts of the tabulator mechanism shown full size. Figs. 4, 5 and 6 are fragmentary vertical fore and aft sectional views, taken transversely, of the parts shown in Fig. 3, Figs. 4, 5 and 6 showing the parts full size and differently disposed as they appear under different conditions of operation. Fig. 7 is a fragmentary view corresponding to Fig. 3, with some ofthe parts omitted but illustrating a different disposition of the parts from that indicated in Fig. 3. Figs. 8 and 9 are detail fragmentary plan views showing full size some of the parts illustrated in Figs. 3 to 7 Fig. l0 is an enlarged detail fragmentary end elevation, with parts in section, of the tabulator lindicating devices and some of detail fragmentary perspective view of aY portion of the automatically actuated controlling mechanism.

I have illlstrated my invention in the present insta. ice embodied in a No. 10 or No.- 11 Remington machine with the ordi' nary tabulator mechanism omitted. I have only shown so much of the machine as may be necessary to arrive at an understanding of my invention in its embodiment therein. While the invention may be readily embodied in either of these machines without modifying, or materially modifying, the structural features of said machines as they now exist except for the omission of the tabulator mechanism ordinarily employed therein, it should bc understood that the invention may be embodied in various vstyles of typewriting machines.

In the construction disclosed in my previous application hereinbefore referredto, the tabulator mechanism is operative at one time as a column selector and at another time` as a denominational selector, depending on the position of the carriage in its travel from side to side of the machine, the travel' of the carriage automatically determining whether the mechanism is operative for column selection or for denominational selection.

In the present construction I have provided means under control of the tabulator keys for automatically controlling the tabulator mechanism to render said mechanism alternatively operative as a column selector and a denominationalselector and have also provided means under control of the tabulator keys for alternately exposing first one and then another of two series of tabulator indices in register with the tabulator keys, accordingly as they are operative for column or 'denominational selection.

The frame of the machine comprises a base 1, corner posts 2 and a top plate ,3. The type actions are of the usual construction, each comprising a key lever 4 fulcrumed on a fulcrum bar 5 secured to the base of the machine4 and having a finger key 6 at 'the keyboard of the machine. Each key lever 4 is connected to a returning spring 7 attached at one end to the key lever and at its opposite end to a hook 8 fixed to the base of the machine. Links 9 and 10 and a sublever 11 are interposed between each key lever and its associated typebar 12, the latter being pivoted to swing upwardly and rearwardly against the front face of a rotative platen 13. A universal bar 14 extends transversely' beneath the key levers 4 and is connected at its ends to upwardly extending links 15 which in turn are connected to crank arms 16 that project rearwardly from a rock shaft 17 mounted at its ends inv the base of the machine. A centrally disposed rearwardly extending arm 18 also extends from said rock shaft and is connected at its rear end to an upwardly extending link 19. This link in turn is connected to a forwardly projecting arm 20 of a dog rocker 21 which carries a feed dog 22 coperative with a double escapement wheel 23. This escapement wheel is carried at the rear end of a shaft which rotates in a bearing 24 fixedto the top plate of' the machine. VThe forward end of the es-' capement wheel shaft carries a feedI pinion 25 with which a feed rack 26 is adapted to mesh. This feed rack is carried by rearwardly extending arms 27 pivoted at 28 to upwardly extending lugs 29 on a carriage, which latter is designated as a wholeby the reference numeral 30. The carriage is formed with oppositely grooved guide .rails or guide ways`31 inwhich anti-friction balls or rollers 32 are received. These anti-friction balls or rollers are also received in oppositely grooved fixed guide rails 33 supported on the top plate of the machine. The rotative platen 13 is supported in the carriage in the usual manner. A spring drum 34 is connected by a band 35 to a bracket arm 36 secured to the carriage at the right-hand end porti'on thereof. This spring is eective to propel the carriage from right to left, or in the direction of its feed under'the control of the escapement mechanism.

f The parts thus far described constitute .This gear is fixed to the upper end of a driving shaft 41 which extends through bearing openings in the top plate and in the base of the machine. The upper end portion of the shaft also extends through a bearing member 42 formed with a-flange 43 secured to the top plate of the machine by screws 44. The hub 45 of the gear wheel bears against the upper end of the bearing member 42 to. sup-` port the gear wheel and shaft in position.

.The lower end of the driving shaft`41 extends through a-bearing opening in a supporting plate 46 which is fixed to the base of the machine in any suitable manner.

Thus in the presentinstance I have secured the supporting plate 46 in place by screws 47 which are received in tapped openings in the base of the machine andare each provided with a hexagonal portion 48 by which the Vscrew may bethreaded into its opening.

' porting a plate 46 in position is the same as r tric in any one of the different rotative pois disclosed in my previous applica-tion hereinbefore referred to and further description thereof is deemed unnecessary. The ,lower end of the driving shaft 4l where it eX- tends beneath the supporting plate 46 is provided with a driving sprocket wheel 5l detachably securedto the shaft by a nut 52 threaded onto the lower end of the shaft to couple the driving wheel and the shaft in the Same manner as is disclosed in my previous a-pplication referred to above. The sprocket wheel 5l engages an endless driving band or sprocket chain 53 which passes Varound and engages idler sprocket wheels 54, 55 and56. A headed shoulder screw 57 constitutes a support and pivot for the sprocket wheel 55, the threaded end of the screw being received in a tapped opening in the supporting plate 46. A like pivot screw 58' constitutes a support and pivot for the sprocket wheel 56. The sprocket wheel 54 receives a bearing on an eccentric 59 through which a headed bearing screw 60 passes. The threaded end of this screw is received in a tapped opening in the plate 46, the eccentric being clamped between the head of the screw and the plate to secure the eccensitions to which it may be adjusted. This construction is similar to the corresponding Iconstruction disclosed in my previous application and is for the purpose of taking up any undue slack in the sprocket chain. It will be seen that the relative disposition of the three --sprocket wheels 51, 54 and 56 is eEective to maintain'vthe sprocket chain in effective engagement with the driving sprocket wheel 51 as well as with theV sprocket wheels 54 and 56.

The straightlength of chain which eX- tends between the sprocket wheels 55 and 56, and which is indicated at 53,is guided `constitutes a guide and supporting face for the inner edge of 4the straight length of chain 53a in the movement of the chain from one of the sprocket wheels 55, 56 to the other. A lower guide plate 63 is arranged parallel with the supporting plate 46 and is connected thereto by the screws 62. The chain is `thus confined between thev lower and upper faces of theplates 46 and 63 respectively to guide and maintain the chain against lateral defiection in its movement from one of the sprocket wheels 55, 56 to the other. In addition to the means thus far described for guiding the sprocket chain, I have provided a guide plate 64 which v.is xedly connected to the guide plate 63 Vby, screws 65, spacing sleeves or washers 66 being interposed between the plates 64 and 63. The rear edge of the guide bar 64 is received between the links 67 of the sprocket chain and is adapted to bear against pivots 68 which unite the links, as shown Vmore clearly in Figs. 4, 5 and 6. The plate 64 is therefore effective to prevent the chain from buckling when the stops engage and from moving forward in the guide formed by the members 64, 63, 61 and 46, the chain being guided on four sides by these members in the passage of the chain from one of the sprocket wheels 55, 56 to the other. One of the links 67 is formed with an outwardly extending projection 69 that constitutes a stop, as will hereinafter more clearly appear. The companion link 67 on the other side of the chain is also formed with a corresponding projection 70 which likewise constitutes astop. These two stops, therefore,- are arranged to travel side by side with the working faces thereof in the same plane, although the two stops have different Vpaths of movement with the chain, the path of movement of one stop being above and parallel with that of the other. It will be understood from the foregoing description that the chain 53 is connected to move in unison with the carriage and that the stops 69 and 70 are likewise connected to move in unison withthe carriage, although the stops 69 and 70 move in the direction of the arrow in Fig. 2, or from left to right, between' the sprocket wheels 55 and 56 as the'carriage moves from right to left or in the direction of its feed. In the present instance the gearing between the carriage and the sprocket chain is as four to three, so that the stops 69 and 70 move at a slightly slower rate of speed than the clarriage; This,`however, may be varied to suit the conditions presented, as pointed out in my previous application.

l have provided a series of key controlled traveling chain driven stop 70. Thus it will be seen thatthese parallel guide plates 63 and 64 are provided with registering slots 71, 72, respectively, which extend fore and aft of the machine from the edges of the guide plates in which they are formed.

Plate-like sheet metal stops 73 are received in these slots.

` In the present instance I have shown ten stops 73, all of which are similar in construction and are received and guided in ltheir movements fore and aft of the maof the stop. The upper end of the U-shaped member on each stop form engaging noses or pawls 76, for purposes which will hereinafter appear. The rear end of each stop 73 is cut out, as at 77 and is formed with an engaging portion 78 for coperation with a stop 126 and with an engaging portion 79 for coperation with the traveling stop 70. A tabulator push key 80 is connected to each stop 73 by a push rod 81 which extends rearwardly from its key and is received in the U-shaped member 75 of the associated stop 73. The rear end of each push rod'81 is turned at substantially a right angle to the length of the rod, as indicated at 82. This bent end of the rod projects through the bearing opening 74 in the associated stop and constitutes a connecting'means by which the stop is connected to move fore and aft of the machine with the stop rod, but by which connection a slight pivotal movement may be given each stop 73 around the associated bent end 82 as a pivot, for purposes which will presently appear. Each push rod 81 carries a leaf spring 83 which bears at its rear free end upwardly against the forward end portion '.75 of the associated stop .73, to maintain it normally seated against its push rod 81. Each leaf spring 83 is preferably formed at its attaching end with encircling bands or clamps 84, which partly surround the associated push rod 81 to secure the leaf spring to the rod. The

forward ends of the push rods extend through guide openings in a member 85 which is secured by screws 86 to the base of the machine at the forward end thereof. The member 85 is in the nature of a casting provided with a perforated iiange 87 (see Fig. 11) to which the forward ends of contractile returning springs 88 are connected. The rear ends of these springs are connected to screws 89 threaded into collars 90 which surround the rods 81'and are maintained in their adjusted positions along the rod by the set screws 89 bearing at their inner ends against the rods 81. Each rod 81 also carries a sleeve 91 (Fig. 11) which is adjustably secured thereto by a set screw 92. Each Aas "sleeve 91 constitutes an adjustable abutment which co-acts with the casting 85 to limit the forward movement of the associated stop rod 81 and the parts controlled thereby. From an inspection of Figs. 1 and 2it will be observed that the bent ends, 82 of the stop rods are received between the guide plates 63 and 64 and extend crosswise of the slots 71 and 72 respectively therein These bent ends 82 therefore co-act with the plate 64 to support the rear ends of the stop rods 81 and the stops 73 carried thereby but afford a fore and aft movement of the stops in the guide slots of the plates 63 and 64 and also afford a slight pivotal movement of the stops, as hereinb'efore explained.

A universal bar 93 extends beneath the guide plate 64 and is provided at its ends with rearwardly extending arms 94. Beneath the Auniversal bar is a bracket arm 95 which extends parallel with the lower face of the guide plate 64 and has a foot piece 96 which bears against the guide plate 64 and is secured thereto by one of the screws 62. The bracket 95 is therefore fixed to the plate 64 and constitutes a support for the universal bar 93 and by whlch it is guided and supported in its movement fore and aft of the l machine. The rearwardly projecting arms 94 of the universal bar are pivotally connected at 98 with depending crank arms 99 which project froma rock shaft 100. This rock shaft is supported at its ends by bearing screws 101 received in tapped eppen ings in the base of the machine. A crank arm 102 which extends downwardly and then forwardly and then upwardly and rearwardly from the rock shaft 100 is connected at 103 to a link 104. The upper end of this link is pivoted at one end 105 to a lever-like ycarriage releasing device 106 which is pivoted at 107 to a `bracket 108 secured to the top plate of the machine. The forward end of the releasing device is provided with an off-set shoe 109 which extends beneath the feed rack 26.y The rock shaft 100 is also provided with a depending crank arm 110 to which one `end of a contractile spring 111 is fixed, the opposite end of said `spring being connected to the extending end 112 of the right-hand screw 47 by which the supporting plate 46 is held in place. The power of the spring 111 is exerted to turn the rock shaft 100 and move Ythe carriage releasing device to normal position, as shown in Fig. 1. From an inspection of this figure it will be understood that each key controlled stop 73, where it extends beneath the guide plate 63, is adapted 'to engage the universal Vbar 93 in the rearward movement of the stop. The effect of this is to move the universal bar rearwardly, thereby rocking the shaft 100 and actuating the carria e releasing device 106 to elevate the rac 26, thereby releasing the carriage from control of its escapement mechanism. This same rearward movement of a key controlled stop is eiiective as hereinbefore pointed out to bring the'engaging portion 7 9 on the projected stop into the path of the chain driven `stop while the engaging portion 78 on the projected stop is maintained out of the path of traveling chain driven stop or engaging device (i9, as will be clearly understood from an inspection of Fig. 4.

From the foregoing description it will be understood that pressure exerted against any of the tabulator keys 80 is eiectiveto move the corresponding stop 73 into the path of the chain driven stop 70 and to simultaneously effect arelease of the carriage.

The carriage being freed from the control f of its escapement mechanism will be propelled from right to left, under the action of its spring drumruntil the chain driven stop 70 co-acts with the projected stop 73 to arrest the carriage in the columnar position determined by the particular stop 7 3 which has been moved to operative position. lYhen pressure on the actuated tabulator key is released the projected stop 73 will return to normal position and the carriage will be restored to control of the escapement mecha! msm.

It will be seen that the ten key controlled stops 73 are arranged at unvariable distances apart, which in the present instance we will assume corresponds to ten letter spaces of the carriage. 1t follows, theretore, that throughout the travel of the carriage from side to side oi' the machine any one of ten columnar fields, each occupying ten letter space positions, may be selected at will by the actua-tion of the tabulator keys 80, which at this time constitute column selecting keys.

From an inspection of Fig. 2 it will be seen that a series of tabulator indices 113 are provided. which indices are adapted to register with the tabulator keys 80 'to aid the operator in selecting the column. It will be seen that these indices read progressively from left to right in their natural order of the columns on the paper. This is due to the fact that the chain driven stop 70 in co-acting with the key controlled stop 73 for column selection moves from lett to right during the movement of the carriage from right to left.

l have provided means whereby when a column selection is made the tabulator mechanism will be automatically controlled so that the next actuation of a tabulator key 8O is effective to select a denominational position ot' arrest within the selected columnar field. 114, which is substantially U-shaped in cross section, as will be seen upon reference to F 14, is mounted to straddle a supporting bar 115 which is rectangular in cross section. Pins 116 extend. across the opening rihus a bar. member or carrierformed by the U-shaped member and are arranged beneath the supporting bar 115 to prevent an upward displacement of the bar 114 lfrom its supporting bar and to afford a longitudinal movement of the member 115 on the supporting bar. One of these pins 116 is extended beyond the outer side of the member 114 and forms means by which a contractile spring 117 may be connected therewith, the opposite end oi. this spring being connected to an arm 118 by which one end of the bar 115 is supported. A pin 119 which extends upwardly from the supporting bar 115 Ico-acts with and limits the move ment of the member 114 to the left, as the parts appear in Fig. 3. The opposite end of the supporting bar 115 is supported by an arm 120. The connection between the 4supporting bar 115 and the arms 118 and 120 is effected by projecting the ends of the bar 115 through rectangular openings in the arms 11S and 120 and inserting pins 121 through -transverse openings in the bar 115 on the inner and outer sides of both of the arms 118 and 120 so as to lock the bar 115 against longitudinal movement in the bearing openings in these arms. The arm 120 extends through an opening 123 in the xed supporting plate 46 (see Fig. 3) to guide the arm 120 and the parts carried thereby. The lower edge of the arm 120 is turned at right angles to the plane thereof, as -indicated at 124, where it abuts the lower face oi the vixed supporting plate 46 to limit the upward movement of the arm 120 and the parts carried thereby.` The arms 118 and 120 are pivoted at their forward ends on a pivot rod 125. The frame formed by the pivoted arms 118, 120 and the cross or supporting bar 115 is therefore mounted for swinging movement around the pivot rod 125. The purpose of this swinging movement of the supporting bar 115 is to bring about an operative connection between the member 114 and the chain driven stop or engaging device 69 when the supporting bar swings down to the position represented in l*1 igs. 5 and 7, and to'efiect a disconnection between the member 114I and the chain driven stop 69 when thesupporting bar 115 is in the normal or elevated position shown in Figs. 3 and 4.

The member 114 is in the nature of a stopcarrying bar provided With a series of stops 126. These stops are spaced at equal distances apart throughout, or substantially throughout, the length of the stop bar i114. There is provision made in the present in` stance for writing in as many as seven denominational positions within any columnar field bythe spacing between these stops 126, as will hereinafter appear. The bar is also provided with a series of engaging devices 12?7 which are uniformly spaced apart and correspond substantially to the spacing of the key controlled stops 73.- It willl be observed that each of these stops 127 has a rear beveled'face 127n for purposes which will be hereinafter explained. When they f longitudinally of the column stop bar. If,

therefore, when the bar 114 is in the operative position and a key controlled stop 73 be projected rearwardly to the operative posi-l tion, as shown in Fig. 6, the engaging portion 78 thereof will be brought into the path of`one of the stops 126. The movement of the stop 73 to operative ,position was effective to release the carriage through the uni'- versal bar 93 in a manner hereinbefore ei;- plained. The released carriage is effective,

therefore, lto transmit movement throughlthe gea`r40, driving shaft 4l, and driving sprocket 51 to the chain` The stop carrying br 114 at this time being operatively connected to the chain will receive a limited movement to the right with the chain until the neXt adjacent stop 126 to the left of the projected stop 73 engages the latter and thus arrests the carriage in the proper denominational position determined by the particular tabulator key 80 which has been actuated. The e'ect of this operation is to transmit varying extents of movement to the stop carrying .bar 114, dependingl on the particular key controlled stop 73 which has been projected to operative position. This variable movementof the stop carrying bar is due/to the fact th"at there isa constantly varying relation between the stops -126 and the stops 73 with which they co-act. This is best illustrated in Fig. 3 from which it will be observed that the working 'face of the first ofthe series of stops 126, counting from left to right, and which working face is in` dicated by the dotted line a, is one unit of distance from the Working face of the associated key controlled stop 73, the working face of the latter being indicated by the dotted. line b. Comparing these lines for each successive pair of coperative stops 73 and 126, it will be seen that they increase a unlt of distance. Each unit of distance designated corresponds to a letter space position of the travel of the carriage. It will be understood, therefore, that the rst pair of stops from the left co-act vto afford a rdrop of the carriage a distance of one ,letter space; the next pair for two letter spaces; the next pair for three; the next for four; the next for five; the next for six;

y l5 n mi the next for seven. The higher the denominational position the sooner the carriage is to be arrested in its travel. It follows, therefore, that at the selection of the highest denomination, or' the one containing digits of the highest order, the least amount of drop of the carriage is effected. Therefore, the two co-acting stops 73 and 126 at the left-hand, of the series determine the highest denominational position of arrest, whereas the two co-acting stops 73 and 126 at the right-hand of the series afford the ,longest extent of drop of the carriage for vgriting in the lowest denominational positin, or at the decimal position.

I have provided means for automatically shifting the stop carrying bar 114 into and out of operative connection with the carriage, such mechanism being controlled by the operation of the tabulator keys. From an. inspection of Figs. 1, 2 and 15, it will be observed that a rotative shaft 128 is provided with bearing pins 129 at its ends, such bearing pins being received in vertically j disposed slotted openings in supporting arms 130. These arms are provided with ears 131 which are fastened by screws 132 to the supporting plate 46. The shaft 128 is thus supported for rotative movement4 and extends beneath the various key levers 4 and above the push rods 81 of the key controlled, tabulator stops. The shaft 128 at that portion thereofwhich is arranged 4, 5 and 6, it will be seen that the up erV faces of the pawls 76 are so di osed t at they co-act normally with a flat ace 135 of the ratchet bar, while in the drawings'pawls are` shown out of coperation with the coacting flat face 135. This is so shown merely for the purpose of clearness of illustration and it should be understood that the pawls are` normally in contact with oneof these faces 135. Therefore the pawls 76 under the action of the springs 83 constitute detents which tend to prevent an accidental rotative movement of the ratchet bar when one of the sto s 73 is shifted to operative position, asin icated in Fig. 6. During this rearwardmovement of a. stop to operative position the stop may receive a slight piv- 'otal movement around its pivot 82 and elevated position.

I the arms 118 and 120, aswill 'y `4o'- j Vcarrying bar 114 is maintained in its lowerbe understood that aftera stop has been appear. 'Each Aendof the rock shaft 128, which carries or is formed as a part of. the

ratchet bar 133, is formed with a cam 136, each of which cams is triangular in cross section (see Fi 15). These cams, as Will be understood rom' reference to Fi 2, 4, 5 and 6, are arranged beneath the arms 118 and `120, the lower edges of 'the latter bearing. against the faces'of the cams 136 and being held in contact therewith by gravity, although one or more springs may-.be employed to isuref proper downward movements of the arms 118 and 120 and the parts carried thereby. From an inspection of Fig. 4 it will be understoodithat when a corner 137 of each of the triangular cams is uppermost, las shown in this gure, the arms 118 and 120 will be maintained in the At this time ,the stop carrying bar 114 is maintained uppermost and out of coperative relation and opera-V tiveoonnection with the chain driven stop 69. When, however, a Hat face 138 of each cam 13,6 is presented for co` eration with se understood from an inspection of Fig. 5, these arms are in the lowermost'position andthe stop most position where one of the engaging members 127 on'the stop carrying bar will oo-'act with the traveling stop 69. At this time,yth erefore, aV movement of the chain driven-stop 69 is `effective to carry the stop carrying barwith it a' predetermined distance, orfuntil thel stop carrying bar is arrested through the coperation of one of the stops 126 thereon with a key controlled stop 73 which has been projected to operative position.

Assume-that the parts are in the normal position and that the operator desires to select a columnar position of arrest, and that this column is, say, the third column controlled by the'third key 80, counting from leftv to right. The effect of anroperationof this key is to move the third key controlled stop to operative position as shown in Fig. 4, where the engaging portion 79 thereof extends into the path of the traveling stop 7 0, and the same actuation of the key 80 is likewise effective to` release the carriage. `The carriage will move from right to left until the traveling stop 70 in its movement from left to right is arrested by the projected key controlled stop. During the return movement of the projected key controlled stop the pawls 76 thereon will engage 'the lowermost tooth 134 on the ratchet bar, turning the ratchet bar one-sixth of a revolution and bringing a `fiat face 138 on each of the cams 136 into position for coperation with the arms 118 and 120, as shown in Fig. 5. The movement of the cams 136 thus effected brings about a lowering of the stop carrying bar 114 to the position shown in Figs. 5 and 7 where the third engaging member 127, counting from left` to right, is interposed in the path of the chain driven stop 69. The effect of the operation'of the third key for column selection work, therefore, is to automatically effect an operative connection between the carriage and the stop bar 114 to render the tabulator mechanism effective for denominational work. The operator, we will assume, next desires to secure the arrest of the carriage in the fourth or 100 denominational position. The operator will then push the seventh tabulator key, counting from the left, rearwardly, which key is designated in Fig. 12 by the index numeral 100". The effect of this is to project the associated key controlled stop 73 rearwardly tothe operative position, as shown in Figs. 6 and 7 and to bring the engaging portion 78 on the key controlled stop into the path of the fifth stop 126, counting from left to right, on the stop carrying bar 114, at the same time effecting a release of the carriage. The stop carrying bar, which at this time is coupled up to move in unison with the carriage in the manner hereinbefore described,

lines the key conti-olled stop by which the third columnar .position of arrest of the carriage was attained` Aand have also shown in fulllines the seventh key controlled stop and the positions that the parts assume at the instant the carriage'is arrested in its 100 denominational position by the coperation of the seventh key controlled stop with the co-acting stop 126 on the stop carrying bar.

In order to facilitate an understanding of the different operating views, it might be well to explain that Fig. 3 represents the parts as they appear in the normal position, with the stop carrying bar 114 out of operative connection with the carriage; that Figs. 4 and 8 show corresponding positions of the parts when a key controlled stop has been actuated for column selection; that Figs. 5 and 9 show corresponding positions of the sof lstops and as denominational key and stlps;

` parts when an actuated key has been released and the key returned to normal position after a column has been selected; and that Figs. 6 and 7 show corresponding positions ofthe parts when a key has been actu'- ated for denominational selection and the carriage is arrested in its denominational position Within a previously selected columnar field.

From the foregoing description it will be understood that the operation of the tabulator mechanism automatically renders the same ke s and key controlled sto s alternately e ective as column selecting eys and that' the tabulator keys themselves are e ective to automatically bring about this change. rby which the tabulator mechanism is alter-` nately effective as a column selector and as a denominational selector; thatwhen the Jkey i controlled stops 73 are operative as column selecting'stops they co-act only with lthe traveling ystop -70 connected with the "carhasv may be employed for both column and de nominati'onal selection, I- have provided means which are automatically actuated to yexpose .one-or another of two series of tabu-y latorindices, accordingly as the mechanism "is'operated, as a column selector or as a denominational selector.. Upon reference to 'Figs 2-and 15'it will be seen that the shaft 45j 128 carries a cam 139 which, like the cams [136, 'is triangular in cross section but is disposed on the shaft differently ffrom the cams. 136 so that when a lou7 portion or flat f face l138 of each of the cams 136 is. brought into action the high portion or apex 140 of the cam 139l is-brought intoaction or 1s `uppern'iosaas indicated in Figs. 1, 4 and 15.

On th'other hand, .a flat face 141 of the cam 139gis presented uppermost when the 'high iontions `137 of the cams 136 are presente uppermost, as Willk be understood i A'upon re rence to Fig. 4. From an inspection. 'of i'gs. 1 and 2, it will be seen 'that' a lever 142 extends fore and aft of the machine and' is .fulcrumed-at its rear end'on'the,

fulcrum bar 5 for the keylevers 4. This lever has a depending projection 143 which coperates With the cam 139. The forward end of'thls lever is bent upwardly beneath O5 and forward of the base of the machine at rocking movement.

144, as shown in Figs. 10 and 12. The part 144 is slotted horizontally at 145 for the reception of a crank pin 146. This crank pin is formed at one end of arock shaft 147 -mountedy to turn in bearings 148 supported on the member 85, which is detachably connected to the base of they machine. A plate 149 is bent at one edge, as at 150 (see Fig. l1) to surround the rock shaft 147 to clamp the same and turn with the rock shaft in its flanged 'as at 151 to receive a scale oriindex plate 152, whichmay be covered-by a transparent plate 153 of celluloid` or like material. The space between the flanges llprovides a sight openinglwhich jeXposesthe tabul'ator -indices113 on the plate` 152. ATheseindlces in .the present instance read?from left to 'right in the natural order of the reading on the work sheet andare as `;f.o1loWsf- 1,

The ,member 149 is` f 10 i. That fisto say, assuming that there ,areten columns on the Work sheet,VV if these 'columnsyb'e' lnumbered "progressively from leftto ri ht in :the `natural order lof their reading, e ten numerical indices 1, 2,

order of reading with the. headings on the different .columns on the `Work sheet. It

y.should Abe understood, however, that any suitableyltabulator indicesmay be employed.

The"construAction is such that. the scale plate .152 jandcoverilpplate )153 .may .be removed longitudinally from beneaththe flanges v151 and-another 'scaleplate bearing different indices may befinserted in place with the cover plate 153 overlying the same.

-Arrangedbeneath the plate 149, when the latter'Y is inthe' position shown in Fig. 11, is a container154 which receives an index or scale plate 155 having denominational indices v1,56 thereon. These indices in the present instance comprise the index numerals 100,000 410,000, 1,000 100:,5"1O?,"1"v, which readI from left to rightinthe natural 'order-of. the reading of 'denominationally positioned characters on the lWork sheet. VThe' index-- l plate 155 may also be 'provided witha transparent cover plate of celluloidjonlike material157. l

In the operationof the machine it will be assumed that the'index carrier 149 is in the position shown-in f Fig. r11 so' vthat the' 'index numerals 113 thereon are exposed'to thev View ofthe operator. At ,this time thefmember 149 overlies the vindices `156 so' that the latter cannot beobserved-by the operator."

Anf actuation of a key`80;for column, selection, and the Selectionof which key is aided byfthe index 113'in register therewith, Will result in effecting a rotative movement of the ratchet member 133 during the return movement of the actuated key to nor- 4mal position. The effect of this movement is to produce a one-sixth revolution of the shaft 128, thereby bringing the apex or velevated portion [14.0 on the cam 139 into operative position.. The effect of this movement .use `of such keys as denominational selecting keys.` The parts remain in the positions lini dicated until the next actuation of a key 80,

vwhich keys at this'time are effective as denominational selecting keys, andduring the return movement of such actuated key to normal position the ratchet bar will be given a turn 'of one-sixth of a revolution, thereby again bringing" the low portion of the cam 139 in coperation with the lever 142, lowering the same and allowing the member 14:9

' to return yto the position shown in Figs. 2

and 11, where the column selecting indices 113areagain exposedto the View of the operator. It willl be understood, therefore, that the construction is such that the operation of the tabulator key 80 is effective to alternately expose the column selecting indices l113 and the denominational indices 15,6 in register :with the tahulating`keys in orderto aid Linthe alternative use of these keys for `denominational and column selection. Moreover, it will be understood that the same awl and ratchetmechanism 7 6-13-1, which is effective under thev operation of 'the tabulatorvkeys` to automatically render the tabulatormechanism operative as a column selector and denominational selector, is also effective to automatically control the tabulator indicating mechanism to alternately expose' the column selecting and denominational selecting indices in register with the keys.

1 From an inspection of iig. 1 itwill be understood that there is considerablel lost `motion between the rear edges of the key,

l'controlled'stop' 73v andthe universal release 4 bar 93,' and thatthereis also considerable lost motion between the carriage release shoe 109 and.v the feed racki26 so that the release of the carriage is not 4effected until the last portion of the movement of the' key oon-- trolled stop into' operative positlon. By r'eav son of this factI` am enabled. to vactuate any of the tabulator keys 80 a distance less than that required to effect-garelease of the carriage, but sufficient nevertheless 'to bring about an engagement of the pawls 76 on the actuated stop withV the ratchet bar 133. A release of the key after such an actuation will enable the pawls 76 to rotate the cams may be, and is also effective to shift the scale 'carrying m'ember 149, yet these operations 136 and 139 to bring about a shifting of the mechanism from the position to which it has been set topya position where it will be effective for the other class of tabulating work. For example, if the parts have been set for denominational work an actuation of one of the keys in the manner described will be effective to set the parts for column selection. If, on the other hand, the parts have been set for column selection and it is desired to set them for denominational selection, then an actuation of a key in the manner described is effective to bring about this result.

AThe construction and arrangement of the parts is such that the operator mayV readily effect an actuationof the controlling mechanism by the operation of a key without releasing the carriage by reasonI of the fact f that an additional load is placedfon the key at the last portion of the stroke, due to the additional resistance required to effect a release of the carriage and this-is readily felt by the operator in actuating a key. It Will be understood, therefore, that while an actuation of any of the tabulator keys for a tabulating operation is effective to automatically bring about a coupling up of the stop carrying bar with, the carriage or a disconnection of said bar from said carriage, as the case when desired may be effected independently of the tabulating operation. If, for eX- ample, the carriage should be returned to the right, preliminary to effecting a tabulating operation, and at this time for any reasonthe parts should be set to expose the denominationallindices instead of the column selecting indices, the operator will at once observe this condition and a light pressure onl any key SO, short of that required to effect-a tabulating operation, will be effectlve to reset the parts for column selecting instead of denomina-tional selecting work. The operator may then proceed to effect a column selection and they next operation of a key is effective-for denominational selection Within the previously selected columnar' field. It will be understood, therefore, that each of the keys 80 is not only effective to 11i automatically i control the mechanism vfor stop 7 0 moves progressively from 'left to right past the successive key controlled stops 73 as the carriage. moves from'right 125 to left. It will 'be understood, therefore, thatif the operator shouldthrough a mistake actuatea previously operated key for column selection the carriage will run throughout its length without being arrestla@ ed because the chain driven stop 70 has passed such key actuated stop.- For eX- ample, if the operator. should` actuate the fifth key 80 for column selection, the same being indicated by the index numeral 5 and at the next column selecting operation should actuate the fourth key, indicated by loperatively connected to the chain through the stop 69,` as indicated in Figs. 5 and 7, for denominational work, and the operator should. fail to denominationally select and should attempt to return the carriage to the right to begin a new line, this will result in the following operation ofthe parts: The movement of the carriage to the right will cause the stop 69 to be moved to the left.

When the stop 69 in this movement engagesI the beveled face .on the first of the engaging members 127, it will cause the stop' carrying bar 114 and its supporting bar 115 to be cammed upwardly out of the path of `l the traveling stop 69 and as each successive engaging device 127 is reached, this same camming action will be effected to move the stop carrying bar 114 upwardly and away from the stop 69 so as not to block the movement of the stop-169 in its movement at this time from/ right to left, and no injury can result to the construction from a violent movement of the carriage to the right, even if the operator should forget to denominationally select before returning theA j carriage to begin a new line.

From the foregoing ,description it will be understood that the stops 126 are arranged at fixed unvariable distances apart; that each of these stops is coperative with but oneof the stops 73; that the stops 126 are automatically moved alternately into and out ofoperative position or into and out of a position where the stops 73, when projected, may coperate therewith; that these same movements of the stops 126 result in effecting an operative connection or disconnection'between the stops 126 and the carri'age, to cause the 'stops to move i`n unison with the 'carriage 4o r to enable the carriage to travel independently. thereof; that the stops 73 are fixed against relative adjustment and are spaced apart at ycolumn determining positions, or toaccord to columnar fields to be filled in; that each stop73 has an unvariable path of movement for a single given extent and that all of these stops move a uniform distance; that the stop carrying bar 114 and the stops 126 a column carried thereby remainv at rest during the ordinary step-by-step feed of the carriage and during the column selecting operation; that the bar 114 and the stops 126 move in unison with the carriage only during the denominational selection and after columnar selection has been effected; and that in this movement of the ybar- 114 it moves to any one of a series of positions, which positions correspond to a series of adjacent letter space positions of the carriage.

While I have described with considerable detail one form or embodiment of my invention it should be understood thatfvarious changes may bemade in the construction without ldeparting from the spirit of my invention,land that parts of the structure may be employed without'others.
